To all whom it may concern:

Be it known that l, Ginns P. GOMEZ, a subject of the King of Spain, residing at Miami, in the county of Gila. and State of Arizona have invented certain new and useful Improvements in Drill Qarriages; and I do declare the iollowin to be a iull, clear, and exact description oi the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved mounting for a compressed air-drill of the type used in mining and other similar work and one object of the invention is to provide a device for mounting the drill which will include a tripod having a track connected therewith a carriage being mounted upon the track and including means for engaging threads of the track and feeding the carriage along the track as the drill operates to form a hole in a rock.

Another object of the invention is to so construct the carriage that the means for elude a worm and means for rotatin imparting movement to the carriage may inthe worm including a paddle wheel rotated by means of compressed air which may be drawn from a source of supply or may be obtained from the exhaust of the compressed air drill.

Another object of the invention is to so construct the device that the paddle wheel may be selectively turned to move the carriage along the track towards either end desired.

Another object of the invention is to so construct this (lgvice that the carriage may be operated by hand if so desired.

Another object of the invention is to so construct this carriage that the compressed air drill may be firmly but releasably connected therewith and thus removed when desired.

Another object oi the invention is to so construct the tripod that the. track may be put in place and .releasably connected with a disk forming part of the tripod and the track and carriage placed at a desired angle upon the disk and releasably secured in the adjusted position.

Another object of the invention is to provide improved supporting legs for the tripod, one of the legs being adjustably mounted and releasably held in a set posispaced clamping jaws or blocks 19.

Figure 4 is a vertical transverse sectional view taken along the line l i of Fig. 3.

F i ure 5 is a sectional view taken along the l1ne 55 of Fig. 1.

Figure 6 is a sectional view taken along the line 6-6 of Fig. 3.

Figure 7 is a sectional view taken along the line 7-7 of Fig. 1.

.Figure 8 is a sectional view taken along the line 88 of Fig. 7.

This improved device is provided with a base or tripod including a disk 1 which is positioned vertically and has sockets 2 cast integral therewith in order to support the diverging forward legs 3 which legs are provided with lower sections 4 telescoping in the upper sections and releasably'held in a set position by set screws 5. The rear leg 6 is also provided with a lower section 7 which telescopes in the upper section and is releasably held in a set] position by the set screw 8. The rear leg is carried by a casting 9 which is U-shaped and provided with arms 10 which extend upon opposite sides of the disk and carry a pivot pin or bolt ll'by means of which the disk is rotatably mounted. A clamp or stay-bolt l2 hasits curved or hooked end portion positioned in a slot 13 formed in one of the legs 10 and fitting into a selected notch 1% formed in the disk 1 so that when the securing nut 15 which is carried by the threaded end portion of this belt as shown in. Figs. 7 and 8, is turned to tighten the clamp, the disk will be firmly gripped and the adjustable legs securely held in a set position. It will thus be seen that by proper adjustment of the rear leg 6 the height of the tripod can be controlled.

The track 16 has its upper face cut to provide the threads 17. This track is positioned above the disk and is provided at its lower edge with a head 18 forengagement by the These clamping jaws or blocks 19 are'cut to engage and conform to the curvature of the disk 1 and bolts are passed through these blocks so that the blocks can be drawn together into tight binding engagement with the bead 18 and disk 1 and thus firmly hold thetrack in engagement with the disk with the track extending horizontal or at a desired incline. One end of said track-is provided with a socket 21 so that if it is desired to increase the length of the track, a second track section having an extended forward end portion may be put in place with the extended forward end portion fitting into the socket 21. The second track section would have a construction similar to the main track section shownin Fig. 1 except thatthe forward end portion would be extended for fitting into the socket instead of having the forward end portion'cut away as shown at 22to provide a seat'for the spring clip 23. This clip 23 is secured by a bolt 24 and extends upwardly to engage the drill steel 25 and guide movement of this drill steel when the drill is in operation. I

The carriage is provided with an upper plate 26 which rests upon the threaded head of the track and is provided with depending side ribs 27 which extend upon opposite sides of the track as shown clearly in Fig. 5. Securing strips 28 are riveted or otherwise firmly connected with these depending side flanges andextend beneath the side portions of the track head as shown in this figure,

' so that the carriage may move longitudinally of the track but may not become disconnected from the same. The lower strips 28' extend beyond the rear end of the upper plate and are provided with upwardly extending lugs 29 thus providing a seat between the lugs 29 and the rear end of the plate 26 to receive the base 30 of a housing 31. The housing 31 issecured to the extended rear end portions of the strips 28 by bolts or similar removable fasteners 32 and it will thus be seen that when desired this housing may be removed for the purpose of cleaning the housing and mechanism contained therein 'and for making necessary repairs.

' The housing 31 is formed in two sections 33 and 34'which are releasably connected by bolts 35 so that the housing may be taken apart to permit of access to the interior thereof. From an inspection of Fig. 3, it

- will be seen that the housing which is hollow is formed to provide a chamber 36 in which a worm 37 is rotatably mounted and engages the teeth of the rack 17. This-worm is provided with shaft extensions 38 and 39- mounted in bearings as shown in this figure, the shaft extension 39 carrying a gear 40 which meshes with a smaller gear 41 positioned in the chamber 42 formed in the-enlargement 43 of the housing. This gear 41 is carried by a .shaft 44 which extends through the fan chamber 45 of the housing sleeve valve is provided witha handle 48 by means of. which it may be turned as desired and is provided with a socket 49 at its outer end which is held in placeby the turning handle 48 and serves as a securing element to prevent longitudinal movement of the sleeve valve. This socket49 receivesone end portion of a hose 50 by means of which com.- pressed air willbe fed to the fan housing. The sleeve valve is provided with an outlet assage 51 and from an inspection of Fig. 4, it will be readily seen that when the device is in operation, the sleeve valve may be turned to direct the air current over or under the shaft 44 thus causing the fan or rotor 46 to rotate in a desired direction during passage of the air through the fan housing and out through the outlet openings 52.

When this support is In use, the com-- pressed air drill 53 will b put in place as shown in Fig. l and secured by the clamps 54 carried by the upstanding ears 55 carried by the upper plate of the carriage. The usual air pipes for supplying air to the compressed air drill will be connected with this drill and the pipe 50 may be connected with the exhaust of the compressed air drill or with a suitable source of compressed air such as a compressed'tank. The drill, steel ex- 1 tends through the guide 23 and the steel will be held in the proper position and prevented from having excessive side movement when the drill is in operation. As soon as the air is turned on, the air passing through 105 the pipe 50into the fan housing Wlll engage the blades of the fan or rotor 46 and this will rotate the shaft 44 thus rotating the worm 37 through the medium of the gears 40 and 41. As the worm 37 rotates, the carbe operated to advance the carriage to feed the drill steel into the. opening or hole formed in the rock and the valve can then be turned to reverse the rotation of the rotor and return the carriage to the rear end portion of the track. If it is desired to operate the return by hand, the crank- 55 will be put in place and releasably secured I by the spring 56. When desired the various elements forming this drill support can be taken apart, repaired or cleaned and the de- 1 vice reassembled. I I claim: Y 1.
